Suggestions
You should fix up the house, the door needs to go on the left side and the windows on the bottom are reversed, whilst on the top they go the other way around. Make sure you use the red roof or atleast fix up the blue one. You should download GoldMap and a Gold rom, open it in GoldMap and copy it, edit it a bit to your liking :P. When doing the ledges make sure you put in the right corners or add room so you can. When doing the trees try to make sure theres no gap into the other map, the screen may stuff up and glitch your game.
